Abstract: A fixed-side connecting portion 151 is provided on an end of the fixed bar 141 while a movable-side connecting portion 152 is provided on an end of the movable bar 142. An air clamp 16 is housed within the fixed bar 141. By pneumatically driving the air clamp 16 while the movable-side connecting portion 152 is superimposed on an upper side of the fixed-side connecting portion 151, a clamp member 165 protrudes from a case 161 to be downwardly rotated and holds the movable-side connecting portion 152 against the fixed-side connecting portion 151. Since the clamp member 165 is pneumatically driven, a die replacement time can be shortened. In addition, since the air clamp 16 is housed within the fixed bar 141, the size of a transfer feeder 41 can be reduced.

Abstract: There is described a feed mechanism for a feed table for translating sheet metal blanks from as automatic notching curling and beading machine to a bodymaker in the process of tin box manufacture. The mechanism comprises a pair of reciprocally drives longitudinal feed bars provided with spring loaded pawls in their upper surfaces which engage behind the edges of the blanks during a forward motion and slide beneath the blanks during a reverse motion. The difficulty of altering the lateral displacement of the respective feed bars to allow the table to transfer blanks of different sizes is overcome by using a telescopic fixing member which can be extended to an infinitesimal degree and then secured. In practice, both the longitudinal feed bars are secured to a reciprocally driven transfer table within the stationary feed table, and it is the connection of the feed bars to this table that is achieved with telescopic fixing members.
